Apple TV+ has dropped the trailer and release schedule for Slow Horses Season 5, based on Mick Herron’s novel London Rules. The espionage thriller returns with six new episodes starting September 24, 2025, followed by weekly drops through October 29, 2025.
Why This Matters Now
This release continues Slow Horses’ brisk pace—five seasons in just over three years—and comes amid renewed interest in the spy drama’s dark humor and offbeat characters. The intensified focus on tech-savvy Roddy Ho and a rising political thriller angle position the show to capture both longtime fans and newcomers this fall.
Plot Preview: New Dangers at Slough House
Season 5 picks up with Slough House in chaos. A shocking mass shooting and a near-fatal incident involving Roddy Ho kick off a wave of bizarre events across London. Rumors swirl—Roddy’s glamorous new girlfriend may be a setup, and a mysterious group seems intent on destabilizing city politics.
The MI5 misfits must connect the dots before chaos engulfs the capital. Jackson Lamb’s principle—“the London Rules: cover your back”—remains central under mounting pressure.
Cast and Characters: Familiar Faces + New Additions
Gary Oldman returns as Jackson Lamb, sardonic head of Slough House. He’s joined by Kristen Scott Thomas (Diana Taverner), Jack Lowden (River Cartwright), Saskia Reeves, Rosalind Eleazar, Jonathan Pryce, and Christopher Chung, who steps into greater prominence as Roddy.
Nick Mohammed (Ted Lasso) joins as special guest Zafar Jaffrey, ambitious mayoral candidate—adding political intrigue to the mix.
Release Schedule & Streaming Availability
Season 5 launches September 24, 2025, with the first two episodes. Apple TV+ will then air one episode weekly, every Wednesday, culminating with the finale on October 29.
Episodes typically drop at 3 a.m. ET / midnight PT, though some users report access as early as 9 p.m. ET the prior evening.
The series is exclusive to Apple TV+, starting with a seven-day free trial, after which the subscription costs $12.99/month.
Roddy Ho: From Comic Relief to Central Figure
Christopher Chung’s Roddy Ho moves from quirky side character to core driver of the narrative. The season opens with him nearly killed in a hit-and-run, then obliviously grooving through London—lost in new romance.
Chung highlights Roddy’s unwitting complicity: his excess confidence fuels events that spiral out of control. He also jokes about experimenting with flamboyant hairstyles to express the character’s self-discovery.
Production Notes and Future Seasons
Season 5 completes Mick Herron’s London Rules arc and marks a turning point for the showrunner, Will Smith. Apple TV+ previously confirmed Seasons 6 and 7, though Slow Horses will continue under new leadership—Gaby Chiappe as head writer for Season 6 and Ben Vanstone for Season 7.
The pace of production remains remarkable: seasons are filmed back-to-back, which has kept the show fresh and release gaps minimal.
What to Watch Next
Viewers are now watching how this tech-driven, politically tinged season unfolds. Key points of interest remain:
- Roddy’s vulnerability or newfound savvy—what does his romance mean?
- Political layers—how will the plot impact London’s mayoral race?
- Lamb’s leadership—can Slough House keep their backs covered amid escalating threats?
Summary
Slow Horses Season 5 debuts on September 24, 2025, with six episodes streaming weekly on Apple TV+. It spotlights Roddy Ho’s dramatic rise amid citywide turmoil and political schemes. The full ensemble returns, with Nick Mohammed as a guest star. The show remains one of Apple TV+’s fastest-moving, most critically acclaimed hits.
